LMF Location Management Function

4 Overview
The Location Management Function (LMF) is the network entity in the 5G Core Network (5GC) supporting the
following functionality:
- Supports location determination for a UE.
- Obtains downlink location measurements or a location estimate from the UE.
- Obtains uplink location measurements from the NG RAN.
- Obtains non-UE associated assistance data from the NG RAN.
Figure 4-1 provides the reference model (in service based interface representation and in reference point
representation), with focus on the LMF:

5 Services Offered by the LMF
5.1 Introduction
The LMF offers to other NFs the following services:
- Nlmf_Location
5.2 Nlmf_Location Service
5.2.1 Service Description
The Nlmf_Location service enables an NF to request location determination (current geodetic and optionally civic
location) for a target UE.
5.2.2 Service Operations
5.2.2.1 Introduction
The service operations defined for the Nlmf_Location service are as follows:
- DetermineLocation: It provides UE location information to the consumer NF.
5.2.2.2 DetermineLocation
5.2.2.2.1 General
The following procedures are defined, using the "DetermineLocation" service operation:
- Retrieve UE Location
5.2.2.2.2 Retrieve UE Location
This procedure allows a consumer NF to request the location information (geodetic location and, optionally, civic
location).
NF Service
LMF
Consumer
1. POST ./determine-location (InputData)
2a. 200 OK (LocationData)
2b. 4xx/5xx (ProblemDetails)
Figure 5.2.2.2.2-1: DetermineLocation Request
1. The NF Service Consumer shall send an HTTP POST request to the resource URI associated with the
"determine-location" custom operation. The input parameters for the request (external client type, LCS
correlation identifier, serving cell identifier, location QoS, supported GAD shapes….) shall be included in the
HTTP POST request body.
If UE LCS Capability is received in the request indicating LPP is not supported by the UE, the LMF shall not
send LPP messages to the UE in subsequent positioning procedures.
ETSI
3GPP TS 29.572 version 15.5.0 Release 15 9 ETSI TS 129 572 V15.5.0 (2019-10)
2a. On success, "200 OK" shall be returned. The response body shall contain the parameters related to the
determined position of the UE (geodetic position, civic location, positioning methods…).
2b. On failure, one of the HTTP status code listed in Table 6.1.4.2.2-2 shall be returned. For a 4xx/5xx response, the
message body shall contain a ProblemDetails structure with the "cause" attribute set to one of the application
error listed in Table 6.1.4.2.2-2.
6 API Definitions
6.1 Nlmf_Location Service API
6.1.1 API URI
The Nlmf_Location service shall use the Nlmf_Location API.
The request URI used in HTTP request from the NF service consumer towards the NF service producer shall have the
structure defined in clause 4.4.1 of 3GPP TS 29.501 [5], i.e.:
{apiRoot}///
with the following components:
- The {apiRoot} shall be set as described in 3GPP TS 29.501 [5].
- The shall be "nlmf-loc".
- The shall be "v1".
- The shall be set as described in clause 6.1.3.
6.1.2 Usage of HTTP
6.1.2.1 General
HTTP/2, as defined in IETF RFC 7540 [12], shall be used as specified in clause 5 of 3GPP TS 29.500 [4].
HTTP/2 shall be transported as specified in clause 5.3 of 3GPP TS 29.500 [4].
HTTP messages and bodies for the Nlmf_Location service shall comply with the OpenAPI [14] specification contained
in Annex A.
6.1.2.2 HTTP Standard Headers
6.1.2.2.1 General
6.1.2.2.2 Content type
The following content types shall be supported:
- JSON, as defined in IETF RFC 8259 [13], shall be used as content type of the HTTP bodies specified in the
present specification as indicated in clause 5.4 of 3GPP TS 29.500 [4].
- The Problem Details JSON Object (IETF RFC 7807 [15]). The use of the Problem Details JSON object in a
HTTP response body shall be signalled by the content type "application/problem+json".
ETSI
3GPP TS 29.572 version 15.5.0 Release 15 10 ETSI TS 129 572 V15.5.0 (2019-10)
